December: Mid-Summer Slump and Trade-Wind Drone
December is the hardest month to find quality at Westbrook. Average swell height drops to 5ft (1.6m), period to 8.7s - the lowest of the year - and ideal wind sits at just 14%. The swell direction rose remains in the right quadrant: SSE 20.2%, E 18.6%, SE 16.7%, ESE 14.5%, S 15.7%, ENE 11.7%. But the wind is brutal: NE 19.9%, SSW 17.9%, ENE 13.4%, S 10.6%, while W/WNW/NW/NNW total a paltry 2.8%. True offshore flow is a rare jewel. The daily thermal sea breeze and summer thunderstorms keep the surface lumpy, so even the right direction swells rarely groom up. That said, an early-morning high-tide session on a 3-5ft (1-1.5m) SSE windswell with a light westerly can still be fun. Just keep expectations low and the shortboard in the car. Water temp 24.1°C, air 23.3°C, rainfall 2.95 mm/day.
